Design / Selection
1. Confirm the specifications
Products represented in this manual are designed only or
use in compressed air systems (including vacuum).
Do not operate at pressures or temperatures, etc., beyond
the range o speci ications, as this can cause damage or
mal unction. (Re er to the speci ications.)
Please contact SMC when using a luid other than com-
pressed air (including vacuum).
We do not guarantee against any damage i the product is
used outside o the speci ication range.
2. Actuator drive
When an actuator, such as a cylinder, is to be driven using
a valve, take appropriate measures (cover installation or
approach prohibition) to prevent potential danger caused
by actuator operation.
3. Intermediate stops
For 3 position closed center or double check valve style, it
is di icult to make a piston stop at the required position
accurately and precisely due to the compressibility o air.
Furthermore, since valves and cylinders are not
guaranteed or zero air leakage, it may not be possible to
hold a stopped position or an extended period o time.
Please contact SMC i it is necessary to hold a stopped
position or an extended period o time.
4. Holding pressure including vacuum)
Since the valves are subject to air leakage, they cannot be
used or applications such as holding pressure (including
vacuum) in a pressure vessel.
5. Not suitable for use as an emergency shutoff
valve, etc.
The valves listed in this manual are not designed or
sa ety applications such as an emergency shuto valve. I
the valves are used or the mentioned applications,
additional sa ety measures should be adopted.
6. Release of residual pressure
For maintenance purposes install a system or releasing
residual pressure. Especially in the case o 3-position
closed center valve or double check valve type, ensure
that the residual pressure between the valve and the
cylinder is released.
7. Double solenoid type
When using the double solenoid type or the irst time,
actuators may travel in an unexpected direction
depending on the switching position o the valve.
Implement measures to prevent any danger rom
occurring when operating the actuator.
8. Ventilation
Provide ventilation when using a valve in a con ined area,
such as in a closed control panel. For example, install a
ventilation opening, etc. in order to prevent pressure rom
increasing inside o the con ined area and to release the
heat generated by the valve.
9. Extended periods of continuous energization
• I a valve will be continuously energized or extended
period o time, the temperature o the valve will increase
due to the heat generated by the coil. This will likely
adversely a ect the per ormance o the solenoid valve
and any nearby peripheral equipment. There ore, when
it is continuously energized or the energized period per
day is longer than the de-energized period use a DC
speci ication valve.
• For applications such as mounting a valve on a control
panel, incorporate measure to limit the heat radiation so
that it is within the operating temperature range. For
example, the temperature will be high when a 3 station
mani old or larger is put next to other valves and
continuously energized.
10. Do not disassemble the product or make any
modifications, including additional machining.
It may cause human injury and/or an accident.
1. Momentary energization
I a double solenoid valve is operated with momentary
energization, it should be energized or at least 0.1
second. However, depending on the condition o the
secondary load, it should be energized until the cylinder
reaches the stroke end position, since there is a
possibility o mal unction.

2. Leakage voltage
Take note that the leakage voltage will increase
when a resistor is used in parallel with switching
element or a C-R circuit (surge voltage suppressor)
is used or protecting a switching device because o
the passing leakage voltage through the C-R circuit.
The suppressor residual leakage voltage should be
as ollows.
DC coil: 3% or less o rated voltage
AC coil:20% or less o rated voltage
3. Solenoid valve drive for AC with a solid state
output SSR, TRIAC output, etc.)
1) Current leakage
When using a snubber circuit (C-R element) or surge
protection o the output, a very small amount o
electrical current will continue to low even during the
OFF state.
This results in the valve not returning. In a situation
where the tolerance is exceeded, as in the above case,
take measures to install a bleeder resistor.
2) Minimum allowable load amount (Min. load current)
When the consumption current o a valve is less than
the output’s minimum allowable load volume or the
margin is small, the output may not switch normally.
Please contact SMC.
4. Surge voltage suppressor
I a surge protection circuits contains nonstandard diodes,
such as Zener diodes or varistor, a residual voltage that is
in proportion to the protective circuit and the rated voltage
will remain. There ore, take into consideration the surge
voltage protection o the controller.
In the case o diodes, the residual voltage is appro-
ximately 1V.
5. Operation in a low temperature condition
It is possible to operate a valve in extreme temperature,
as low as -10
o
C. Take appropriate measures to avoid
reezing o drainage, moisture etc. in low temperature.
6. Mounting orientation
Mounting orientation is ree.
Mounting
1. Operation manual
Install the products and operate them only a ter reading
the operation manual care ully and understanding its
contents. Also, keep the manual where it can be re erred
to as necessary.
2. Ensure sufficient space for maintenance ac-
tivities
When installing the products, allow access or main-
tenance.
3. Tighten threads with the proper tightening
torque.
When installing the products, ollow the listed torque
speci ications.
4. If air leakage increases or equipment does not
operate properly, stop operation.
Check mounting conditions when air and power supplies
are connected. Initial unction and leakage tests should
be pre ormed a ter installation.
5. Painting and coating
Warnings or speci ications printed or a ixed to the
product should not be erased, removed or covered up.
Please consult with SMC be ore applying paint to
resinous parts, as this may have an adverse e ect due to
the solvent in the paint.

1. Lubrication
1) The valve has been lubricated or li e by the actory, and
does not require any urther.
2) I a lubricant is used in the system, use class 1 turbine oil
(no additive), ISO VG32.
Once a lubricant is used in the system, lubrication must
be continued because the original lubricant applied
during manu acturing will be washed away.
I turbine oil is used, re er to the Material Sa ety Data
Sheet (MSDS) o the oil.
3) Please contact SMC regarding class 2 turbine oil (with
additives), ISO VG32.
Air Supply
1. Type of fluids
Please consult with SMC when using the product in
applications other than compressed air.
2. When there is a large amount of drainage.
Compressed air containing a large amount o drainage
can cause mal unction o pneumatic equipment. An air
dryer or water separator should be installed upstream
rom ilters.
3. Drain flushing
I condensation in the drain bowl is not emptied on a
regular basis, the bowl will over low and allow the
condensation to enter the compressed air lines. It causes
malu unction o pneumatic equipment.
I the drain bowl is di icult to check and remove,
installation o a drain bowl with an auto drain option is
recommended.
For compressed air quality, re er to SMC’s Best Pneumatics
catalog.
4. Use clean air.
